The ATV1200A20003333 is a medium-voltage AC drive rated for 1672 kW motor power with a supply voltage range of 2970-3630 V AC. This places it squarely in the MV drive class for large induction or synchronous motors — think mainline conveyors, mine hoists, large pumps, or compressor trains where a 480 V low-voltage drive would require impractical current levels. The 18-pulse diode rectifier input topology delivers significantly lower line current harmonics than a standard 6-pulse drive, often eliminating the need for external harmonic filters in medium-voltage installations. Line current is 410 A with an apparent power rating of 2000 kVA. Overload capability follows a dual profile: 1.2 x In for 60 seconds (standard) or 1.5 x In for 3 seconds, with a high-overload variant offering 1.5 x In for 60 seconds and 1.85 x In for 3 seconds. This matters when sizing for applications with intermittent peak loads — the 60-second window at 1.5x covers most starting and short-term overload events without oversizing the drive.
Floor-standing construction and cooling demands
This drive ships as a floor-standing enclosure with separate airflows for the transformer and power cells. Physical footprint is substantial: 1500 mm depth (standard efficiency) or 1700 mm (high efficiency), 4560 mm or 4860 mm width respectively, and 2670 mm height. Plan the installation bay accordingly — this is not a wall-mount unit. Forced convection cooling moves 19800 m³/h (standard efficiency) or 23100 m³/h (high efficiency) of air. The noise level is 80 dB — ear protection zones around the drive are expected in operation. Operating position is vertical within ±10 degrees. The product composition includes a phase-shifting transformer, 9 power cells, medium-voltage arrestors, cooling fans, and a human-machine interface. Power connections use M10 screw-type terminals accepting up to 6 x 40 mm² cable per phase, with entry from bottom or top.
Compliance, isolation, and fault handling
CE marked and designed to EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (adjustable speed drives), and EN/IEC 61800-5-1 (electrical safety). Pollution degree 2 per the safety standard, overvoltage category II. Electrical isolation between power and control circuits is provided. Dielectric strength is 10 kV AC between earth and power terminals. The drive withstands a prospective line fault current of 31.5 kA for 150 ms — this sets the upstream protection coordination requirements. Ground fault protection is integrated into the drive. Altitude derating applies above 1000 m: 0.6 % current reduction per 100 m up to 2000 m. Relative humidity range is 0-90 % standard, 0-95 % optional. Vibration resistance is 4.9 m/s² at 10-50 Hz.
Control interfaces and I/O
Four software-configurable analogue inputs accept 0-20 mA or 4-20 mA signals at 24 V max with 250 Ohm impedance. Two analogue outputs are similarly configurable. Discrete inputs number 6 standard, expandable to 10 optional. External control supply is 220 V AC at 3 kVA; an optional 220 V AC/DC supply is available. The internal cooling fan supply runs at 380 V AC. An integrated EMC filter is included.
